[0036] Preferred embodiments will now be described with reference to the accompanying drawings. Figure 1 Here is an overview of the sound source device 1 in this embodiment. Figure 1 This is a diagram showing the appearance of the sound source device 1. The sound source device 1 is an electronic device that outputs (emits) musical sounds based on performance information received from electronic percussion instruments such as the electronic drum 30. The sound source device 1 is equipped with a display for various settings or... Figure 2 (a) ~ Figure 2 (e) The impact surface display Gd1 and other liquid crystal displays (LCDs) 2, which will be described later.

[0037] An electronic drum 30 and an electronic cymbal 40 are connected to the sound source device 1. The electronic drum 30 is an electronic percussion instrument that sends performance information corresponding to the user H's striking of the drumhead to the sound source device 1. The electronic drum 30 has a striking surface that is circular when viewed from above. The performance information sent from the electronic drum 30 may include: striking information of the striking surface (skin) or edge, the position or speed of the striking surface when it is struck, the position and pressure of the striking surface when it is pressed, and the speed of the edge when it is struck. However, other information related to striking the electronic drum 30 may also be sent.

[0038] The electronic cymbal 40 is an electronic percussion instrument that sends performance information corresponding to the user H's striking of the striking surface to the sound source device 1. In this embodiment, an electronic hi-hat that imitates a hi-hat is used as the electronic cymbal 40, but it is not limited to this, and electronic cymbals that imitate other cymbals such as rhythm cymbals may also be used as the electronic cymbal 40.

[0039] The electronic cymbal 40 also has a striking surface that appears circular when viewed from above. The playing information sent from the electronic cymbal 40 can include: striking information of the striking surface or the bell, the striking position or speed of the striking surface, the pressing position when the user H pinches the outer perimeter of the striking surface to produce a choke, or the speed at which the bell is struck. However, other information related to striking the electronic cymbal 40 can also be sent.

[0040] In this embodiment, the electronic drum 30 and electronic cymbals 40 are composed of a so-called "digital drum pad" capable of calculating performance information including the striking position. The method for detecting the striking position of the digital drum pad uses a known method, such as the method disclosed in Japanese Patent Application Publication No. 2018-36641. Furthermore, in this embodiment, the sound source device 1 is connected to the electronic drum 30 and electronic cymbals 40 via a wired connection, but it is not limited to this and can also be connected wirelessly.

[0041] The playing information based on the user H's striking of the electronic drum 30, etc., is sent to the sound source device 1. The sound source device 1 generates and emits musical tones based on the playing information received from the electronic drum 30, etc. At this time, especially for beginners whose playing skills are not proficient, the user H sometimes wants to grasp where the electronic drum 30, etc., is actually struck while mastering the pronunciation of the musical tones.

[0042] Therefore, in this embodiment, by displaying a strike surface display Gd1, which mimics the strike surface of an electronic drum 30 or the like, on the LCD 2, and displaying a strike position display HP based on the strike position on the strike surface display Gd1, the user H can specifically grasp the position where the electronic drum 30 or the like is struck. (Refer to...) Figure 2 (a) ~ Figure 5 To illustrate the impact surface display Gd1, etc.

[0043] Figure 2 (a) is a diagram of LCD 2 showing the percussion surface display Gd1 for the electronic drum 30. When the electronic drum 30 is struck, the percussion surface display Gd1, which mimics the percussion surface of the electronic drum 30, is displayed on LCD 2. The percussion surface display Gd1 contains an image of the percussion surface of the electronic drum 30 in two dimensions (i.e., a plane), and its shape is circular, just like the percussion surface of the electronic drum 30.

[0044] The impact surface display Gd1 is provided with a central area display Ca, an edge area display Ra, and a radial display HL. The central area display Ca is a circular display area displayed in the center of the impact surface display Gd1. In the electronic drum 30 of this embodiment, when the center of the impact surface and a certain range around the center of the impact surface are hit, it is determined that the center of the impact surface has been hit.

[0045] Therefore, in the impact surface display Gd1, the area corresponding to a certain range in the electronic drum 30 that is determined to be struck in the center of the impact surface is displayed as the central area display Ca. Through the central area display Ca, the user H can determine the area in the electronic drum 30 that is determined to be struck in the center of the impact surface.

[0046] Furthermore, in this embodiment, since the certain range of the electronic drum 30 is formed into a circular shape, the central area display Ca of the striking surface display Gd1 is also formed into a circular shape, but it is not limited to this. For example, if the certain range is formed into a rectangular shape, the central area display Ca is also formed into a rectangular shape, etc., so that the shape of the central area display Ca can be arbitrarily changed according to the shape of the certain range.

[0047] The edge zone display Ra is a display area set along the outer periphery of the striking surface display Gd1, formed based on the edge area in the electronic drum 30.

[0048] The radial display HL is a linear display component that radiates from the central area display Ca towards the edge area display Ra. In this embodiment, eight radial display HLs are provided in the impact surface display Gd1. When an area other than the center and edge of the impact surface is hit in the electronic drum 30, the impact position display HP based on the impact position is displayed on the impact surface display Gd1, but the impact position display HP is displayed on the radial display HL closest to the received impact position.

[0049] Furthermore, the number of HL lines in the radiographic display is not limited to 8. For example, when the detection accuracy of the impact position of the electronic drum 30 is high, the number of HL lines in the radiographic display can be more than 8, and when the detection accuracy of the impact position of the electronic drum 30 is low, the number of HL lines in the radiographic display can be less than 8.

[0050] In addition, such as Figure 2 As shown in (a), the arrangement of radial displays HL is not limited to the uniform arrangement of the impact surface display Gd1. For example, when there are mixed positions with high impact detection accuracy and low impact detection accuracy in the impact surface of the electronic drum 30, the density of radial displays HL (i.e., the number of radial displays HL per unit area) can be increased in the area of ​​the impact surface display Gd1 that corresponds to the position with high impact detection accuracy, and the density of radial displays HL can be decreased in the area of ​​the impact surface display Gd1 that corresponds to the position with low impact detection accuracy.

[0051] Here, the hit position display HP shown on the radial display HL will be explained. The hit position display HP is a black ring-shaped display component that appears at the corresponding position on the hit surface display Gd1 when an area of ​​the electronic drum 30, excluding the center and edges of the hit surface, is hit. The hit surface display Gd1 contains an image of the hit surface of the electronic drum 30 in two dimensions, therefore the hit position display HP is also positioned in a two-dimensional position (planar position) on the hit surface display Gd1.

[0052] Thus, a percussion surface display Gd1, which mimics the two-dimensional image of the percussion surface of the electronic drum 30, is displayed, and a percussion position display HP, configured based on the two-dimensional position of the impact received from the electronic drum 30, is displayed on the percussion surface display Gd1. That is, by displaying the percussion surface display Gd1, which mimics the percussion surface of the electronic drum 30 represented by a plane, and the percussion position display HP, configured based on the two-dimensional position on the percussion surface display Gd1, the user H can more specifically grasp the position where the electronic drum 30 is struck.

[0053] Additionally, eight radial lines (HL) are displayed on the percussion surface display (Gd1), and the percussion position display (HP) is displayed on the radial line (HL) closest to the percussion position received from the electronic drum 30. That is, since the display of the percussion position display (HP) is confined to the eight radial lines (HL) from the entire percussion surface display (Gd1), the processing load on the sound source device 1 associated with the display of the percussion position display (HP) is reduced, allowing for rapid display of the percussion position display (HP).

[0054] Next, refer to Figure 2 (b) ~ Figure 2 (e) illustrates the impact surface display Gd1 when each part of the electronic drum 30 is struck. Figure 2 (b) is a diagram showing the Gd1 display on the striking surface when the center of the striking surface of the electronic drum 30 is struck. Figure 2 (c) is a diagram showing the impact surface display Gd1 when the edge of the electronic drum 30 is struck. Figure 2 of (d), Figure 2 (e) are diagrams showing the impact surface display Gd1 when the electronic drum 30 is subjected to an open rim shot.

[0055] like Figure 2 As shown in (b), when the center of the electronic drum 30's striking surface or a certain area surrounding the center of the electronic drum 30's striking surface is struck, the display pattern (e.g., color) of the central area display Ca of the striking surface display Gd1 changes. Furthermore, in the figure, when the center of the electronic drum 30's striking surface or the aforementioned certain area is not struck, as... Figure 2 As shown in (a), the central area Ca is displayed in white. This occurs when the electronic drum 30 is struck in the center of its striking surface or within a certain range. Figure 2 In (b), the central area Ca is shown in shaded.

[0056] Thus, based on the change in the display pattern of Ca in the central area of ​​the drum surface display Gd1, it indicates whether the center of the drum surface 30 or a certain range has been struck. Therefore, the change in the display pattern of Ca in the central area can be called "striking position display". By comparing the user H's own striking near the center of the drum surface 30 with the accompanying change in the display pattern of Ca in the central area, the user H can more specifically determine where the center of the drum surface 30 or the certain range is where the strike surface is determined to have been struck.

[0057] Furthermore, the display pattern of Ca in the central area is not limited to the above situation. For example, it can be set to display Ca in black when the center of the electronic drum 30's striking surface or the certain area is not struck, and display Ca in yellow when the center of the electronic drum 30's striking surface or the certain area is struck, and other display pattern changes.

[0058] Next, refer to Figure 2 (c) illustrates the impact surface display Gd1 when the edge of the electronic drum 30 is struck. For example... Figure 2 As shown in (c), when the edge of the electronic drum 30 is struck, the display pattern (e.g., color) of the edge area display Ra of the strike surface display Gd1 changes. In the figure, when the edge of the electronic drum 30 is not struck, as shown... Figure 2 As shown in (a), the edge area Ra is displayed in white when the edge of the electronic drum 30 is struck, as... Figure 2 As shown in (c), the edge area Ra is displayed in shadow.

[0059] Thus, when the edge of the electronic drum 30 is struck, the display pattern of Ra in the edge area changes, allowing the user H to easily grasp the situation. Furthermore, the change in the display pattern of Ra in the edge area is not limited to the described scenario. For example, it could be configured such that Ra is displayed in light blue when the edge of the electronic drum 30 is not struck, and in red when the edge of the electronic drum 30 is struck, or other similar display patterns.

[0060] Next, refer to Figure 2 of (d), Figure 2 (e) illustrates the impact surface display Gd1 when the electronic drum 30 is subjected to an open rim impact. For example... Figure 2 As shown in (d), when an open-edge impact occurs where the center or a certain range of the electronic drum 30's striking surface is simultaneously struck as well as the edge, the display patterns of the central area display Ca and the edge area display Ra change simultaneously. Furthermore, as... Figure 2 As shown in (e), when an open-edge strike is performed where the center of the electronic drum 30's striking surface or a position further outward than the aforementioned range and the edge are simultaneously struck, the striking position display HP is displayed at the striking surface display Gd1 corresponding to the outer periphery position, while the display form of the edge area display Ra changes.

[0061] Thus, when the electronic drum 30 is hit by an open edge, the user H can easily grasp the situation of the electronic drum 30 being hit by an open edge and where the edge and the striking surface are hit together by the open edge, based on the changes in the display form of Ra in the edge area and the changes in the display form of HP in the striking position corresponding to the position where the electronic drum 30 is hit.

[0062] Next, refer to Figure 3 (a) ~ Figure 3 (c) illustrates the striking surface display Gd2 used for the electronic cymbal 40. Figure 3 Figure (a) shows the LCD 2 displaying the striking surface display Gd2 for the electronic cymbal 40. When the electronic cymbal 40 is struck, the striking surface display Gd2, which mimics the striking surface of the electronic cymbal 40, is displayed on the LCD 2. The striking surface display Gd2 includes an image of the striking surface of the electronic cymbal 40 in two dimensions. The shape of the striking surface display Gd2 is formed as a semi-circular shape of the lower half based on a top view of the striking surface of the electronic cymbal 40.

[0063] The striking surface display Gd2 includes a cymbal cap display Ba, a peripheral display Ta along the outer periphery of the striking surface display Gd2, and a radial display HL. The cymbal cap display Ba is a circular display area displayed in the center of the striking surface display Gd2. According to the cymbal cap of the electronic cymbal 40, the cymbal cap display Ba is formed in a circular shape.

[0064] The radial display HL is a linear display component that radiates from the cymbal cap display Ba towards the outer peripheral display Ta. In this embodiment, the radial display HL of the striking surface display Gd2 is provided with 7 lines. Depending on the detection accuracy of the striking position of the electronic cymbal 40, the number of radial display HLs of the striking surface display Gd2 can be set to 7 or more, or 7 or less.

[0065] In the event that an area of ​​the electronic cymbal 40 other than the cymbal cap and outer periphery is struck, and... Figure 2 (a) ~ Figure 2 Similarly, the impact position display HP of the impact surface display Gd1 described in (e) is displayed on the radiation display HL that is closest to the received impact position. The impact position display HP of the impact surface display Gd2 is also configured in a two-dimensional position (coordinates) on the impact surface display Gd2.

[0066] Thus, a striking surface display Gd2, which mimics the striking surface of the electronic cymbal 40, is displayed, and a striking position display HP, configured based on the two-dimensional position of the striking location received from the electronic cymbal 40, is displayed on the striking surface display Gd2. Therefore, similar to the striking surface display Gd1 for the electronic drum 30, the user H can more specifically grasp the position where the electronic cymbal 40 is struck.

[0067] Furthermore, the shape of the percussion surface display Gd1 corresponding to the electronic drum 30 is the same as the shape of the percussion surface of the electronic drum 30 when viewed from above, and is circular. In contrast, the shape of the percussion surface display Gd2 corresponding to the electronic cymbal 40 is a semi-circular shape of the lower half of the shape (circular shape) of the percussion surface when viewed from above.

[0068] The reason is that a strike can be detected on the entire striking surface of the electronic drum 30, whereas a strike can only be detected in the lower half of the striking surface of the electronic cymbal 40 when viewed from above. By forming the striking surface display Gd2 in a shape corresponding to the location where a strike can be detected on the striking surface of the electronic cymbal 40, the user H can easily grasp the area on the striking surface of the electronic cymbal 40 where a strike can be detected.

[0069] Next, refer to Figure 3 of (b) Figure 3 (c) illustrates the striking surface display Gd2 when the cymbal cap of the electronic cymbal 40 is struck and the outer periphery of the electronic cymbal 40 produces a muffled sound. Figure 3 (b) is a diagram showing the impact surface displaying Gd2 when the cymbal cap of the electronic cymbal 40 is struck. Figure 3 (c) is a diagram showing the striking surface display of Gd2 when a muffled sound is produced on the outer periphery of the electronic cymbal 40.

[0070] like Figure 3 As shown in (b), when the cymbal cap of the electronic cymbal 40 is struck, the display pattern (e.g., color) of the cymbal cap display Ba changes. Furthermore, in the figure, when the cymbal cap of the electronic cymbal 40 is not struck, as shown... Figure 3 As shown in (a), the cymbal cap indicator Ba is displayed in white when the cymbal cap of the electronic cymbal 40 is struck, as... Figure 3 As shown in (b), the cymbal cap Ba is shown in shaded.

[0071] Thus, when the cymbal cap of the electronic cymbal 40 is struck, the display pattern of the cymbal cap display Ba changes, allowing the user H to easily understand the impact status of the cymbal cap. Furthermore, the change in the display pattern of the cymbal cap display Ba is not limited to the above scenario. For example, it could be configured such that when the cymbal cap of the electronic cymbal 40 is not struck, the cymbal cap display Ba is displayed in green, and when the cymbal cap of the electronic cymbal 40 is struck, the cymbal cap display Ba is displayed in red, or other similar changes in display pattern.

[0072] In addition, such as Figure 3 As shown in (c), when the user H pinches the outer periphery of the electronic cymbal 40 to produce a muffled sound, while the display shape of the outer periphery display Ta of the striking surface display Gd2 changes, a black ring-shaped display component, namely the muffled sound display CP, is displayed in the outer periphery display Ta at the position corresponding to the pressing position where the electronic cymbal 40 is pressed due to the muffled sound. Thus, the user H can easily grasp the situation of the outer periphery of the electronic cymbal 40 being muffled, and where the outer periphery is being pinched.

[0073] Thus, when the electronic drum 30 is struck, Figure 2 (a) ~ Figure 2 The impact surface of (e) is displayed on LCD 2, showing Gd1, when the electronic cymbal 40 is struck. Figure 3 (a) ~ Figure 3 The striking surface display Gd2 of (c) is displayed on LCD 2. In this embodiment, the striking surface display Gd1 or striking surface display Gd2 displayed on LCD 2 is switched based on the "position type" assigned to the struck electronic drum 30 or electronic cymbal 40 respectively. (Refer to...) Figure 3 of (d), Figure 3 The (e) indicates the location type.

[0074] Figure 3 (d) is a diagram illustrating the method of detecting the strike position of the electronic drum 30. Figure 3 Figure (e) illustrates the method for detecting the striking position of the electronic cymbals 40. In this embodiment, the electronic drum 30 and the electronic cymbals 40 are composed of a so-called "digital drum pad" capable of acquiring performance information including the striking position from themselves, and the methods for detecting the striking position differ between the two.

[0075] like Figure 3 As shown in (d), in the electronic drum 30, the striking position is detected by combining the position Pos_CU on the center-periphery axis from the center Ct to the periphery Ut with the angle Ang centered on the center Ct.

[0076] On the other hand, such as Figure 3As shown in (e), in the electronic cymbal 40, the striking position is detected by combining the position Pos_CU on the center-periphery axis connecting the center Ct to the periphery Ut with the position Pos_LR on the left-right axis connecting the upper end Rt of the right half of the striking surface and the upper end Lt of the left half of the striking surface.

[0077] Hereinafter, the method of detecting the striking position in this type of electronic percussion instrument will be referred to as "position type". In this embodiment, for each position type, a corresponding striking surface display Gd1, striking surface display Gd2, and other display components are assigned. Specifically, for the position types: "center-peripheral axis" and "angle" ( Figure 3 (d) The distribution of the strike surface display Gd1 and the central area display Ca, etc., are display components used simultaneously with the strike surface display Gd1. Figure 2 (a) For position types: “center-peripheral axis” and “left-right axis” assigned strike surface display Gd2 and display components used simultaneously with the strike surface display Gd2 ( Figure 3 (a)).

[0078] Then, user H assigns position types to each electronic percussion instrument connected to the sound source device 1. For example, position types "center-peripheral axis" and "angle" are assigned to electronic drum 30, and position types "center-peripheral axis" and "left-right axis" are assigned to electronic cymbals 40.

[0079] Furthermore, the position type of the electronic percussion instrument being struck among the electronic percussion instruments connected to the sound source device 1 is acquired, and display components such as the strike surface display Gd1 and strike surface display Gd2 that correspond to the acquired position type are acquired and displayed on the LCD 2. Thus, when the electronic drum 30 is struck, the LCD 2 of the sound source device 1 displays, for example... Figure 2 The impact surface display (a) shows Gd1, and when the electronic cymbal 40 is struck, it is displayed on the LCD 2 of the sound source device 1 as shown. Figure 3 The striking surface of (a) shows Gd2.

[0080] Furthermore, the sound source device 1 is configured to connect not only to digital drum pads such as electronic drum 30 and electronic cymbals 40, but also to analog drum pads that only transmit waveforms based on the output values ​​of sensors detecting the impact, i.e., impact waveforms, and emit musical sounds based on the received impact waveforms. Since the impact position obtainable from the impact waveforms received from the analog drum pads is only the "center-peripheral axis" as described above, the position type of the analog drum pads is "center-peripheral axis". Here, refer to... Figure 4 (a) ~ Figure 4 (e) illustrates the impact surface display Gd3 shown on LCD 2 when the simulated impact pad is hit.

[0081] Figure 4 Figure (a) shows LCD 2 displaying the impact surface display Gd3 for simulating a striking pad. When the simulated striking pad is struck, the impact surface display Gd3 is displayed on LCD 2. The impact surface display Gd3 is set to... Figure 2 (a) ~ Figure 2 The strike surface shown in (e) is Gd1, with the same central area shown as Ca, the edge area shown as Ra, and the radial area shown as HL.

[0082] Among them, radiation shows HL and Figure 2 (a) ~ Figure 2 of (e) Figure 3 (a) ~ Figure 3 The impact surface displays Gd1 and Gd2 described in (e) are different, with only one line displayed. This is because the simulated impact pad's position type is "center-peripheral axis," which can only detect impact positions along a single axis. When an area of ​​the simulated impact pad other than the center and edges of the impact surface is impacted, the impact position display HP, based on the impact position, is displayed on the radiation display HL.

[0083] Next, refer to Figure 4 (b) ~ Figure 4 (e) illustrates the impact surface display Gd3 when each part of the simulated impact pad is struck. Figure 4 (b) is a diagram showing the Gd3 display on the impact surface when the center of the impact surface of the simulated impact pad is hit. Figure 4 (c) is a diagram showing the impact surface display Gd3 when the edge of the simulated impact pad is hit. Figure 4 of (d), Figure 4 (e) are diagrams showing the impact surface display Gd3 when the simulated impact pad is hit by an open edge.

[0084] like Figure 4 As shown in (b), when the center or a certain area around the impact surface of the simulated impact pad is impacted, the display pattern (e.g., color) of Ca displayed in the central area changes. Additionally, as... Figure 4 As shown in (c), when the edge of the simulated impact pad is struck, the display pattern of Ra in the edge area changes. Additionally, as... Figure 4 of (d), Figure 4 As shown in (e), when the simulated drum pad is hit by an open edge, the display pattern of Ra in the edge area changes, and the display pattern of HP in the hit position corresponding to the position where the electronic drum 30 is hit or Ca in the center area changes.

[0085] Thus, the display Gd3 for the simulated drum pad also displays the same information as the display Gd1 for the electronic drum 30 or the display Gd2 for the electronic cymbals 40. This prevents the user H from experiencing any discrepancy between the content displayed on the LCD 2 when the simulated drum pad and electronic drum 30 are connected to the sound source device 1 and when the simulated drum pad is struck, and the content displayed on the LCD 2 when the electronic drum 30 is struck.

[0086] Next, refer to Figure 5 To explain the function of the sound source device 1. Figure 5 This is a functional block diagram of the sound source device 1. For example... Figure 5 As shown, the sound source device 1 has a striking surface display component 500 and a striking position display component 501.

[0087] The percussion surface display unit 500 is a component that displays at least two-dimensional images of the percussion surfaces of electronic percussion instruments 550, such as electronic drums 30 or electronic cymbals 40, forming percussion surface displays Gd1 and Gd2. Figure 6 The central processing unit (CPU) 10 described later in (a) is implemented by the strike position display unit 501, which displays a strike position display HP configured based on at least two-dimensional positions of the strike positions obtained from the electronic percussion instrument 550 on strike surface displays Gd1 and Gd2 displayed by the strike surface display unit 500, and is implemented by the CPU 10.

[0088] That is, a percussion surface display Gd1 and a percussion surface display Gd2, which are composed of two-dimensional images that mimic the electronic percussion instrument 550, are displayed, and a percussion position display HP, which is configured based on the two-dimensional position of the strike position obtained from the electronic percussion instrument 550, is displayed at the corresponding position on the percussion surface display Gd1 and the percussion surface display Gd2. By displaying the percussion surface display Gd1 and the percussion surface display Gd2, which are composed of at least two-dimensional images, such as percussion surface display Gd1 and the percussion surface display Gd2 represented by a plane, and the percussion position display HP configured at least two-dimensional positions on the percussion surface display Gd1 and the percussion surface display Gd2, the user H can more specifically grasp the position where the electronic percussion instrument 550 is struck.

[0089] Next, refer to Figure 6 (a) ~ Figure 6 (c) will be used to explain the electrical structure of the sound source device 1. Figure 6(a) is a block diagram showing the electrical structure of the audio source device 1. The audio source device 1 includes a CPU 10, a read-only memory (ROM) 11, a random access memory (RAM) 12, the LCD 2, an external input / output device 13, an audio source 14, and a digital signal processor (DSP) 15, all of which are connected via a bus 16. A digital-to-analog converter (DAC) 17 is connected to the DSP 15, an amplifier 18 is connected to the DAC 17, and a speaker 19 is connected to the amplifier 18.

[0090] CPU 10 is an arithmetic unit that controls the various components connected via bus 16. Flash ROM 11 is a rewritable, non-volatile memory containing a control program 11a, a percussion display table 11b, and a musical instrument information table 11c. When CPU 10 executes control program 11a, it executes... Figure 7 The main processing unit. (Refer to...) Figure 6 (b) and Figure 6 (c) is used to illustrate the percussion display table 11b and the instrument information table 11c.

[0091] Figure 6 (b) is a schematic diagram of the impact display table 11b. The impact display table 11b stores display data related to the display of the impact surface display Gd1, etc., for each position type. For example, for position types "center-peripheral axis" and "angle" (i.e., the case of electronic drum 30), the impact surface display Gd1, the central area display Ca, and the edge area display Ra are correspondingly stored as display data.

[0092] For position types: "center-peripheral axis" and "left-right axis" (i.e., the case of electronic cymbal 40), corresponding display data is established and stored for the striking surface Gd2, cymbal cap Ba, and peripheral display Ta. Additionally, for position types: "center-peripheral axis" (i.e., the case of simulated striking pad), corresponding display data is established and stored for the striking surface Gd3, central area Ca, and edge area Ra.

[0093] Figure 6(c) is a schematic diagram representing the instrument information table 11c. The instrument information table 11c stores the position type for each electronic percussion instrument connected to the sound source device 1. For example, for the electronic drum 30, the position types are stored as "center-peripheral axis" and "angle," and for the electronic cymbals 40, the position types are stored as "center-peripheral axis" and "left-right axis." The instrument information table 11c stores the combination of electronic percussion instruments and position types input by the user H via an input device (not shown) provided on the sound source device 1.

[0094] The position type of the electronic percussion instrument that is being struck is obtained from the instrument information table 11c, the display data corresponding to the position type is obtained from the strike display table 11b, and the strike surface display Gd1, etc. are displayed on the LCD 2 using the obtained display data.

[0095] Return to Figure 6 (a) RAM 12 is a memory that can be rewritten to store various working data or flags when the CPU 10 executes programs such as control program 11a. External input / output device 13 is a device for inputting / outputting information from connected external devices. An electronic percussion instrument such as electronic drum 30 or electronic cymbals 40 is connected to external input / output device 13 to receive performance information from electronic percussion instruments on digital pads or percussion waveforms from electronic percussion instruments on analog pads.

[0096] In this embodiment, USB (registered trademark) is used as the communication standard for the external input / output device 13, but the external input / output device 13 can also be configured with other communication standards, or it can be configured to input / output information from external devices via wireless communication.

[0097] Sound source 14 is a device that outputs waveform data corresponding to the performance information input from CPU 10. DSP 15 is a computing device for processing the waveform data input from sound source 14. DAC 17 is a conversion device that converts the waveform data input from DSP 15 into analog waveform data. Amplifier 18 is an amplification device that amplifies the analog waveform data output from DAC 17 with a specified gain. Speaker 19 is an output device that emits (outputs) the analog waveform data amplified by amplifier 18 in the form of musical tones.

[0098] Next, refer to Figure 7 This will explain the processing performed by the CPU 10 of the audio source device 1. Figure 7 This is a flowchart of the percussion processing. Percussion processing is the event processing performed after the power to the sound source device 1 is turned on, when performance information or percussion waveforms are received from the electronic percussion instrument via the external input / output device 13.

[0099] In the striking process, the striking position is first obtained based on performance information received from a digital percussion pad, such as an electronic drum 30 or electronic cymbals 40, in the electronic percussion instrument (S1). Then, the striking position is calculated based on the striking waveform received from an analog percussion pad in the electronic percussion instrument (S2). The method for calculating the striking position based on the striking waveform in S2 uses a known method, such as the method disclosed in Japanese Patent Application Publication No. 2021-105702. In this embodiment, the processes S1 and S2 are performed in parallel.

[0100] After processing S1 and S2, from the instrument information table 11c (refer to...) Figure 6 (c) Obtain the position type (S3) that matches the electronic percussion instrument whose strike position was obtained or calculated in the processes of S1 and S2. Specifically, determine the electronic percussion instrument whose strike position was obtained or calculated in the processes of S1 and S2 among the electronic percussion instruments connected to the external input / output device 13, and obtain the position type that matches the determined electronic percussion instrument from the instrument information table 11c.

[0101] After processing in S3, from the strike display table 11b (refer to...) Figure 6 (b) Obtain display data that matches the position type obtained in the process of S5 (S4), and confirm whether the display data currently displayed on LCD 2 is different from the display data obtained in the process of S4 (S5).

[0102] If, during processing S5, it is confirmed that the currently displayed data differs from the displayed data obtained during processing S4 (S5: Yes), the currently displayed data is hidden from LCD 2 (S6). After processing S6, the displayed data obtained during processing S4 is displayed on LCD 2 (S7). Thus, the percussion surface display Gd1, etc., corresponding to the previously struck electronic percussion instrument is hidden, while a new display of the percussion surface display Gd1, etc., corresponding to the currently struck electronic percussion instrument is displayed. On the other hand, if, during processing S5, it is confirmed that the currently displayed data is the same as the displayed data obtained during processing S4 (S4: No), processing S6 and S7 are skipped.

[0103] Following the processes S5 and S7, the impact position obtained or calculated in processes S1 and S2 is converted into a display position (S8). Specifically, the impact position is converted so that the impact position obtained or calculated in processes S1 and S2 is positioned at the corresponding position on the impact surface display Gd1, etc. At this time, the impact position is moved so that the impact position is located on the nearest radiation display HL among the radiation displays HL of the impact surface display Gd1, etc.

[0104] Furthermore, the center-peripheral axis position of the strike position obtained or calculated in the processes of S1 and S2 is represented in 128 levels from 0 to 127, thus converting the strike position into 8 levels from 0 to 7. As a result, the number of strike position display HP positions on the radial display HL is reduced from 128 to 8, thereby reducing the processing load of the sound source device 1 associated with the display of the strike position display HP and enabling the strike position display HP to be displayed quickly.

[0105] After processing in S8, based on the strike position converted in processing in S8, the display of strike position display HP, or the display form of strike surface display Gd1, strike surface display Gd3 (central area display Ca or edge area display Ra), and the display form of strike surface display Gd2 (cymbal cap display Ba or peripheral display Ta) are changed (S9).

[0106] Following the processing in S9, further processing of the sound source device 1 (S10) is performed. As part of the further processing in S10, processing for generating musical tones based on received performance information or percussion waveforms and outputting the generated musical tones may be listed. Following the processing in S10, the percussion processing ends.

[0107] The above description is based on the described embodiments, but it is easy to deduce that various improvements and modifications can be made.

[0108] In the described embodiment, in Figure 2 (b) ~ Figure 2 In (e), Gd1 is shown as the striking surface when the edge of the electronic drum 30 is hit or when the electronic drum 30 is hit by an open rim shot. However, Gd1 can also be shown on the striking surface when the electronic drum 30 is hit by a closed rim shot.

[0109] In this case, such as Figure 8 As indicated by the strike surface display Gd10 in (a), the strike position display PP is executed simultaneously with the strike position display HP, at the position in the strike surface display Gd10 corresponding to the position where the strike surface of the electronic drum 30 is pressed due to the damping edge. Through the strike surface display Gd10, the user H can easily grasp the situation of the electronic drum 30 being subjected to the damping edge, and at this time, where the strike surface is struck and thus pressed.

[0110] In the described embodiment, in Figure 3 In the strike surface display of (c) Gd2, the mic is indicated by a black circle, but it is not limited to this. For example, the mic may be replaced by something else, such as... Figure 8The striking surface display (b) shown by Gd20 mimics the muting effect of a human hand, displaying HD. This allows user H to more intuitively understand the muting process of the electronic cymbal 40.

[0111] In the described embodiment, the percussion surface displays Gd1 to Gd3 displayed on LCD 2 correspond only to the electronic percussion instruments that are actually struck, but are not limited to this. They can also simultaneously display the percussion surface displays Gd1 to Gd3 corresponding to all electronic percussion instruments connected to the sound source device 1. For example, such as... Figure 8 As in (c), when an electronic drum 30 and an electronic cymbal 40 are connected to the sound source device 1, it is sufficient to simultaneously display the percussion surface display Gd1 and the percussion surface display Gd2 on the LCD 2. Thus, the user H can immediately determine which electronic percussion instrument is connected to the sound source device 1.

[0112] Alternatively, regardless of whether an electronic percussion instrument connected to the sound source device 1 is being struck, the prescribed percussion surface displays Gd1 to Gd3 can always be displayed on the LCD 2. In this case, the percussion surface displays Gd1 to Gd3, which are pre-specified by the user H, can always be displayed on the LCD 2.

[0113] In the described embodiment, based on the area in the electronic cymbal 40 where the impact can be detected, Figure 3 (a) ~ Figure 3 The impact surface display Gd2 of (c) is formed in a semi-circular shape, but is not limited to this. The impact surface display Gd2 may also be formed in a circular shape, which is the same as the shape of the impact surface of the electronic cymbal 40 when viewed from above. In this case, in the circular impact surface display Gd2, it is preferable that the display form (e.g., color) of the area in the electronic cymbal 40 where an impact can be detected is different from that of the area where an impact cannot be detected.

[0114] In the described embodiment, the percussion surface displays Gd1 to Gd3 displayed on the LCD2 are switched based on the position type of the electronic percussion instrument being struck, but this is not a limitation. For example, other information identifying the electronic percussion instrument, such as its model information, may also be used to switch the percussion surface displays Gd1 to Gd3 displayed on the LCD2.

[0115] In the described embodiment, the impact surface displays Gd1 to Gd3 are set as two-dimensional (planar) images, but are not limited to this. For example, the impact surface displays Gd1 to Gd3 may also be set as three-dimensional (stereoscopic) images. In addition, the impact position display HP is also configured in a two-dimensional position, but is not limited to this, and may also be configured in a three-dimensional position.

[0116] In the described embodiment, linear radial lines HL are displayed on the impact surface displays Gd1 to Gd3, but the embodiment is not limited to this. The radial lines HL may also be other shapes, such as broken lines or curves. Furthermore, the radial lines HL may be omitted from the impact surface displays Gd1 to Gd3.

[0117] In the described embodiment, an electronic drum 30 and an electronic cymbal 40 are used as electronic percussion instruments, but the invention is not limited to these; other electronic percussion instruments such as an electronic conga may also be used.

[0118] In the described embodiment, the control program 11a is configured to be stored in the flash memory ROM 11 of the sound source device 1 and run on the sound source device 1. However, it is not limited to this and may also be configured to run on other computers or electronic devices such as personal computers (PCs), mobile phones, smartphones, or tablets. In this case, it is sufficient as long as a device similar to the external input / output device 13 is provided on the PC or mobile phone and it can be connected to an electronic percussion instrument such as the electronic drum 30.
